Which of the following is a common sign of dehydration in patients?

Dry mouth is a common sign of dehydration in patients because it occurs when the body is not retaining enough fluid to maintain moisture in the oral cavity. This can happen due to various reasons, including insufficient fluid intake or excessive fluid loss through sweating, vomiting, or diarrhea. When dehydration occurs, the salivary glands produce less saliva, leading to a dry sensation in the mouth.

Understanding the signs of dehydration is crucial in a patient care setting, as early recognition can facilitate prompt treatment and prevent more severe complications. Recognizing dry mouth as a symptom can help healthcare providers take necessary steps to rehydrate the patient and restore their fluid balance.

In contrast, increased urine output would typically indicate good hydration or even overhydration, while high energy levels are generally not associated with dehydration; in fact, patients experiencing dehydration often feel fatigued and lethargic due to the reduced availability of fluids for cellular functions. Therefore, recognizing dry mouth as a sign of dehydration is essential for effective patient care.
